A kind of composite natural plant feed additive and application
Technical field
The invention belongs to herding or field of feed, particularly relate to a kind of feed addictive of composite natural plant.
Background technology
The revolution of aquaculture and feed industry has been created in the application of feeding antibiotic and popularization, has promoted economic developing rapidly.But along with antibiotic the abuse for a long time, in a large number brought serious negative effect: the micro ecology of gastrointestinal tract balance of 1) destroying livestock and poultry, interference fowl poultry immune system, the local nospecific immunity system of digestive system, respiratory system and reproductive system particularly, reduce livestock and poultry to the resistance of disease, affect livestock birds health, the sustainable development of serious threat animal husbandry; 2) residual in the livestock products such as meat, egg, milk, the health that directly threatens the people; 3) by the alternative inheritance of antibiotic resistance and the propagation that intersects, disturb infectious human or animal's treatment, improve the dosage of medicine for treatment, the health that indirectly threatens humans and animals.Therefore, the research of feeding antibiotic substitute has become focus, and wherein the natural plants such as plants essential oil, the banksia rose, cordate houttuynia, catechu and active ingredient thereof enjoy people to pay close attention to.
Plants essential oil has the sterilization and anticorrosion function, especially Thymol etc.The banksia rose has promoting qi circulation and relieving pain, regulates the flow of vital energy soothing the liver, and the invigorating the spleen stagnant effect that waits that disappears can be treated stomachache, diarrhoea, tenesmus.Cordate houttuynia has the microbial growths such as the staphylococcus aureus of inhibition, Bacillus influenzae, Diplococcus pneumopniae; Strengthen the body immune system effect, improve leukocytic phagocytosis.Catechu has clearing heat and eliminating phlegm, the effect of the analgesic therapy that promotes the production of body fluid to quench thirst, stops blooding, hygroscopic sore.Above natural plants has possessed the effect of feeding antibiotic by different mechanism, so its composition can more effectively replace antibiotic than one matter, and have advantages of safe, have no drug resistance, meet the healthy aquaculture developing direction.
Summary of the invention
The objective of the invention is to utilize natural plant resource, a kind of alternative antivirus somatotropic agent commonly used is provided, have no side effect, the composite natural plant feed additive of pollution-free, lower cost.
The technical measures that the present invention takes are as follows:
A kind of composite natural plant feed additive, it is characterized in that: it is that wherein said carrier is defatted rice bran with plants essential oil compound, the banksia rose, cordate houttuynia, catechu powder and the carrier composition that 3~5:10~20:15~30:30~50:10~20 mixed preparing form by weight.
Plants essential oil compound in this feed addictive is formed through mixed preparing by 3~5 parts of 5~10 parts of cinnamon oils, 5~10 parts of thyme linaloe oils, lemongrass oil.
The Raw material processing of this composite natural plant feed additive requires: the banksia rose, cordate houttuynia, catechu powder are 80~100 purpose micro mists through super-dry and Crushing of Ultrafine processing; Defatted rice bran is through super-dry and pulverization process 40~60 purpose fine powders.
The using method of feed addictive of the present invention be addition according to feed gross weight meter, be 0.03%~0.5%, directly add in livestock and poultry and aquatic animal feed; Or be mixed and made into pre-mixing agent with carrier; Or be mixed and made into premix, concentrate feed form feed livestock and poultry and aquatic livestock with other feed addictive or feedstuff.
Outstanding advantages of the present invention is: this feed addictive is comprised of natural plant composition, have advantages of safe, have no drug resistance, effectively substitute antibiotics, meet the healthy aquaculture developing direction.This additive can promote growth of animal, improves feed efficiency, reduce disease incident.
The specific embodiment
Embodiment 1
The banksia rose, cordate houttuynia, catechu are reached 80 purpose powder through super-dry and Crushing of Ultrafine processing; Defatted rice bran is reached 40 purpose fine powders through super-dry and pulverization process.Be that 10:10:5 forms the plants essential oil compound through the abundant mixed preparing of liquid mixing equipment (emulsification agitator tank) with cinnamon oil, thyme linaloe oil, lemongrass oil according to volume ratio.Then plants essential oil compound, the banksia rose, cordate houttuynia, catechu powder and defatted rice bran are fully mixed according to the ratio of weight ratio 5:15:20:40:20, namely formed composite natural plant feed additive of the present invention.Weight 0.05% according to feed is added this additive.
This example formula is suitable for weanling pig, and effect is obvious.
With this routine additive weanling pig of feeding.The weanling pig that the body weight of 72 21 disposable wean of age in days is consistent with sex is divided into three groups at random, three repetitions of every component (hurdle), 12, every hurdle.Three groups of basal diets of feeding are consistent.Test one group of interpolation 0.05% composite natural plant feed additive of feeding, test two groups of interpolation 0.04% colistin sulfate pre-mixing agents (containing 10% colistin sulfate) of feeding.Control group fed be not add additive of the present invention and colistin sulfate pre-mixing agent.Fed 14 days, result is as follows:
Add composite natural plant feed additive to the impact of Growth Performance of Weaning Piglets
Annotate: the different lowercase alphabet differentials of colleague's shoulder mark different significantly (P<0.05).Below roughly the same.
Result shows, uses composite natural plant feed additive of the present invention, compares with the blank group, significantly improves weanling pig average daily gain 26.32%, reduces material anharmonic ratio 11.61% and Incidence of Diarrhea 48.26%(P<0.05); Compare with colistin sulfate group (testing two groups), significantly improve weanling pig average daily gain 14.20%, reduce material anharmonic ratio 3.52% and Incidence of Diarrhea 16.82%(P<0.05).
Embodiment 2
The banksia rose, cordate houttuynia, catechu are reached 80 purpose powder through super-dry and Crushing of Ultrafine processing; Defatted rice bran is reached 40 purpose fine powders through super-dry and pulverization process.Be that 10:5:3 forms the plants essential oil compound through the abundant mixed preparing of liquid mixing equipment (emulsification agitator tank) with cinnamon oil, thyme linaloe oil, lemongrass oil according to volume ratio.Then plants essential oil compound, the banksia rose, cordate houttuynia, catechu powder and defatted rice bran are fully mixed according to the ratio of weight ratio 5:15:15:45:20, namely formed composite natural plant feed additive of the present invention.Weight 0.03% according to feed is added this additive.
This example formula is suitable for broiler chicken, and effect is obvious.
With this routine additive Cobb broiler chicken of feeding.240 Cobb meat chicks (male and female half and half) that 1 age in days body weight is basically identical are divided into three groups, eight repetitions of every component (cage), 10, every cage at random.Three groups of basal diets of feeding are consistent.Test one group of interpolation 0.03% composite natural plant feed additive of feeding, test two groups of interpolation 4mg/kg flavomycoins of feeding.Control group fed be not add additive of the present invention and flavomycoin.Fed 42 days, result is as follows:
Add composite natural plant feed additive to the impact of growth of meat chicken performance
Result shows, uses composite natural plant feed additive of the present invention, compares with the blank group, significantly improves broiler chicken average daily gain 16.73%, reduces material anharmonic ratio 10.79%(P<0.05); Compare with flavomycoin group (testing two groups), improve broiler chicken average daily gain 4.22%, significantly reduce material anharmonic ratio 4.52%(P<0.05).
